I have a Sony A7. Will this lens work full frame and auto exposure/focus with a converter? Many thanks.

This lens works on full frame but I am not sure how the electronics would work with a converter

I only use mine as straight Nikon mount. I'd suggest asking the converter companies such as Fotodiox. Also try www.diglloyd.com/articles/ask/lenses-LensAdapters.html

I use it on my Sony a7s and it has provided excellent service and great image quality in a variety of situations, some of them almost completely dark! The a7s completely silent mode with this lens is amazing! Just set it to aperture or shutter priority and auto ISO with the top of 109,000 and watch the miracles happen!

William I am using this device on my Sony A6000 (successor to the NEX-7) and I can control all lens functions including auto focus via the camera. I have not used the A7S, but I assume it would work similarly to the A6000. Happy shooting!!!

No, it is a dt lens which means it is for crop sensors. The a7 is a full frame. On top of that the the a7 uses the e-mount and this is an a-mount meaning it would also require an adapter to work properly.

According to what I have read the A7 has an e mount the same as the NEX cameras. I use the Sigma 19mm on my NEX 6.I however don't know how much coverage you will get for your full frame Sony. The Sigma being designed for the cropped NEX sensor.

There are several mount version of this lens. For your camera, you need to choose sony amount version, it does work. However you need manual focus, AF function is not available with this lens.

Works fine on my A7r. You must use full frame lenses or you'll get vignetting. DX lenses will connect but will create vignetting. To get the A7 or A7r to trigger, you must change a setting in the menus to allow it to trigger with no lens attached.

I use a 70-300 Sigma. It will work but on manual you can zoom all the way and focus yourself. If your on auto focus it will work only till about 200 mm then it won't focus anymore. But this is what happens with this lens. Can say for sure if it will on any other. As for picture quality I did notice a fair difference. Not very clear when zoomed all the way. But need to try with a tripod. I got it for my birding and does not work well for that for me.

Any lens you use will have to be manually focused. If its a canon fd lens it will not work without another converter.

It will only work in manual focus mode with the 50-500mm (i.e. you'll have to focus the lens manually). Like any other 2x converter it will not only double the focal length, but also decrease the aperture by two stop making the lens too dark for any camera to focus automatically (i.e. f/6.3 -> f/18 @ 500mm)!The camera autofocus only works on lens faster than f/2.8, like the 70-200 f/2.8 (or 120-300 f/2.8) for example with this 2x teleconverter

Hi, The lens will work fine with the A7, but because it is designed for APSC it will only provide a circular image on the A7 full sensor. The A7 can be set to crop to APSC automatically to provide an image equivalent to 18mm. This image will only be about 10 mega-pixels. On a recent trip to the Venica Carnival I used a Sigma 12-24mm EX DG ASP HSM II with an LA-EA4 adapter, which worked fine but is somewhat bulky. There is a Rokinon 14mm f2.8 full-frame lens with a Sony FE fitting, but it is manual focus. Used at hyperfocal settings it can be pretty fast because it doesn't need focusing.. good for wide landscapes.Cheers, Eb Hi, The lens will work fine with the A7, but because it is designed for APSC it will only provide a circular image on the A7 full sensor.

I use this lens with my Sony a7 with the Sony LA-EA4 E-Mount to A-Mount Full-frame Adapter. It is manual focus only, so takes time to focus. Nice bokeh, but one thing I found, you can't get close up shots, @3 ft is the closest if I recall. Great, however, for head/shoulder portraits and isolating subjects from background.

Yes, this lens is fully functional with the a7, with the excretion that the image will be cropped. Applying the crop factor to the 12mm FL should give you a relative FL of 18mm.

Hello, this Sony A-Mount to E-Mount Lens Adapter supports 35mm full-frame sensor which means that when you use a full frame lens like 28-75 mm F2.8 SAM (SAL2875) to your Sony A7, there will be no cropping factor. However, using an APS-C format lens like 18-55 mm F3.5-5.6 SAM II (SAL18552) will still give you a cropping factor when use to your Sony A7. Hope this helps. -Ely

It will only work as a manual focus lens and not an autofocus. I havent looked for any manual and autofocus adapters because all the older lenses I have are strictly manual. Even though you can only shoot in manual, the adapter is worth it. :)

Yes... make sure that you see the designation FE..in the lens description. which means full frame, e mount. The A7r needs a full frame lens. If you bought the full frame adaptor, and used full frame 'a' mount lenses with it, the pictures will look good, and the auto focus will work, BUT, the e mount lenses mostly have the electronic stabilizer built into the lens..Pictures look good with this lens and the Great A7r body...(in my use and experience)

Hi - Just double-checked a couple of OM lenses on my Sony a7r using this adapter. I want to make sure I'm completely understanding the question: if you're asking whether there will be any vignetting of the image, the answer is no (except to the extent that a specific lens shows some light falloff at the edges, but that's not an adapter issue, and you'd have the same phenomenon on an OM film body). If the question is whether or not the image will be cropped (using the term to refer to the so-called "crop factor" associated with smaller-than-24x36 sensors): again, the answer's no. OM lenses are full-frame lenses, the a7 is a full-frame body - so no cropping of the image. Hope that's helpful!
